Hi all,

I am just beginning to install and start to implement 'multichain', version 1.6. Currently I want to implemet a demo on my own single system. How can I use a seond server(as in the 'Getting started') web page. Can I use a virtual machine for my second server?

I thank you in advance.

Node2 is getting stuck when trying to connect to Node1

Mon, 05 Mar 2018 11:20:03 +0000

I am using EC2 instances.

I installed multichiain in Node1 and everything works fine.

Then later I did the same in setup in Node2, once after modifying the inbound rules and giving rights to node2 in multichain.

I am able to connect, but connection is not complete, it got stuck as below for a long time.

Unable to retreive params in node2 as well.

ubuntu@ip-172-31-22-80:~$ multichaind chain1@172.31.41.67:9543
MultiChain Core Daemon build 1.0 alpha 26 protocol 10006
Chain chain1 already exists, adding 172.31.41.67:9543 to list of peers
Other nodes can connect to this node using:
multichaind chain1@172.31.22.80:9543
Node started

How do I install and develop on just one Windows 10 instance?

Wed, 07 Dec 2016 13:43:48 +0000

I have installed MultiChain on Windows 10.

Following the instructions on "Getting Started with MultiChain", I did as follows:

1) In one cmd prompt, I executed these commands:

multichain-util create chain1

multichaind chain1 -daemon

Worked fine. So far, so good.

2) In a second cmd prompt, I then execute this command:

multichaind chain1@192.168.1.109:6763

That fails, though, with this message:

-- copy start

MultiChain Core Daemon build 1.0 alpha 26 protocol 10006

IO error: C:\Users\Morten.Helles.EVERYMATRIX\AppData\Roaming\MultiChain\chain1\permissions.db\MANIFEST-000002: The handle is invalid.

ERROR: Couldn't initialize permission database for blockchain chain1. Probably multichaind for this blockchain is already running. Exiting...

-- copy end

What am I doing wrong?

Thanks!
